The AUC and AUA codons in mRNA both specify isoleucine. What feature of the genetic code explains this?

complementarity

nonsense codons

universality

degeneracy

Degeneracy

Explanation:

There are 4 nucleotide bases and they can form a lot of different codons - about 64 different codons There are only 20/21 amino acids, not enough for each of the codons

As a result, codons have to "double up" and share amino acids because there is only a limited number of these that they can code for
